Abstract
The present disclosure relates to an electronic device, a wireless communication method, and a computer-readable medium. According to one embodiment, provided is an electronic device comprising a processing circuit and used for a user equipment side; the processing circuit is configured to control to transmit a non-precoded first uplink reference signal, receive feedback by a base station regarding the first uplink reference signal, and sending, on the basis of said feedback, a pre-coded second uplink reference signal.
Claims13
An electronic device for a base station, the electronic device comprising processing circuitry configured to perform control to:
- receive, from a user equipment, a precoded first uplink reference signal which is transmitted using two or more uplink reference signal resources;
- transmit a feedback to the user equipment based on the first uplink reference signal;
- and
- receive a precoded second uplink reference signal which is transmitted by the user equipment based on the feedback,
- wherein the processing circuitry is configured to perform control to receive the first uplink reference signal with a first period, and to receive the second uplink reference signal with a second period shorter than the first period.
A non-transitory computer readable medium comprising computer readable instructions which, when executed, cause a computer to:
- receive, from a user equipment, a precoded first uplink reference signal which is transmitted using two or more uplink reference signal resources;
- transmit a feedback to the user equipment based on the first uplink reference signal;
- and
- receive a precoded second uplink reference signal which is transmitted by the user equipment based on the feedback,
- wherein the first uplink reference signal is received with a first period, and the second uplink reference signal is received with a second period shorter than the first period.
A method for communications by a base station comprising the steps of:
- receiving, from a user equipment, a precoded first uplink reference signal which is transmitted using two or more uplink reference signal resources;
- transmitting a feedback to the user equipment based on the first uplink reference signal;
- and
- receiving a precoded second uplink reference signal which is transmitted by the user equipment based on the feedback,
- wherein the first uplink reference signal is received with a first period, and the second uplink reference signal is received with a second period shorter than the first period.
